Description David Jorm 2014-04-28 07:06:10 EDT 
It was found that the fix for CVE-2014-0094 was incomplete. The Struts 2 ParametersInterceptor was updated to block access to the 'class' parameter, but not all forms in which this parameter can be specified were blocked. A remote attacker could use this flaw to manipulate the ClassLoader used by the application server running Struts 2. This could lead to arbitrary remote code execution under certain conditions.

This flaw is reported to affect Struts 2.0.0 through to Struts 2.3.16.1. It is corrected in 2.3.16.2.

Comment 1 David Jorm 2014-04-28 07:10:05 EDT 
Statement:

Not Vulnerable. This issue only affects struts 2, it does not affect the versions of struts as shipped with various Red Hat products. A similar issue exists in struts 1, identified by CVE-2014-0114.

Applications using a third-party struts 2 library, deployed to Red Hat JBoss products, may be affected. Additional information can be found in the Red Hat Knowledgebase article: https://access.redhat.com/site/solutions/800293
